We explore the phenomenological implications of two minor zeros in neutrino mass matrix using trimaximal mixing matrix. In this context, we analyze 15 possible classes of two minor zeros in neutrino mass matrix and found that only two classes, namely class \(A_1\) and class \(A_2\) are allowed. We predict the absolute values of total neutrino masses, effective Majorana masses, the effective electron anti-neutrino mass, and Majorana CP-violating phases for these two classes. Furthermore, we analyze the correlations of neutrino oscillation parameters. We discuss a flavor model within the seesaw model along with \(Z_{8}\) symmetry group for generating these classes.

摘要

We explore the phenomenological implications of two minor zeros in neutrino mass matrix using trimaximal mixing matrix. In this context, we analyze 15 possible classes of two minor zeros in neutrino mass matrix and found that only two classes, namely class \(A_1\) and class \(A_2\) are allowed. We predict the absolute values of total neutrino masses, effective Majorana masses, the effective electron anti-neutrino mass, and Majorana CP-violating phases for these two classes. Furthermore, we analyze the correlations of neutrino oscillation parameters. We discuss a flavor model within the seesaw model along with \(Z_{8}\) symmetry group for generating these classes.
